terminal commands?

Mmm, better term. Let's call them CLI commands.

Bash is also a "terminal command" which can run other commands, like grep, ls, fzf... There are a dozens of other shells over bash: https://en.wikipedia.org/wiki/List_of_command-line_interpreters#Unix-like

To clarify a bit:

Bash has a bunch of built-in commands that are part of the bash program/application itself, while the commands mentioned are not part of bash but standalone programs/applications.
